摘　　要：本文主要探究了办公建筑南向窗综合式遮阳构件的尺寸模拟计算和优化设计。文章使用Ecotect数值模拟分析软件建立了单间标准办公室及南向窗模型,并选择室内热环境和光环境两项参数作为分析计算指标。随后对比分析了无遮阳和安装综合式遮阳构件下办公室室内太阳辐射量和照度值、采光系数的变化情况。结果表明,南向窗综合式遮阳构件的尺寸为竖向高度2.2 m、水平宽度2.6 m、西翼外伸长度1.07 m、东翼外伸长度为0.96 m时,能够起到夏季最大程度遮挡太阳直射辐射的效果,降低了建筑制冷能耗,同时不影响室内正常采光,兼顾了节能效益和实用价值。This paper mainly explores the dimensional simulation calculation and optimization design of the integrated sunshade component of the south facing window of the office building.The paper established a single room standard office and southbound window model by Ecotect numerical simulation analysis software,and selected indoor thermal and light environment as the analysis and calculation indexes.Then compare and analyze the changes of solar radiation,illumination value and lighting coefficient in office without shading and integrated shading components.The results show that when the size of the south-facing window integrated sunshade component is 2.2 m vertical height,2.6 m horizontal width,1.07 m west wing extension length and 0.96 m east wing extension length,it can shield the direct solar radiation to the maximum extent in summer,reduce the building cooling energy consumption,and do not affect the normal indoor lighting,taking into account the energy saving and practical value.
